' Our present'invention relates to an imroved sticker band intendedparticularly or use in a photographic roll film cartridge. Roll filmcartri gee of a common type m- 6 'clude lon strips of interwound backing"paper an film, the latter being secured at one end by a sticker to thepaper, and the other end being free but havin a sticker attached. Therehave been mar et'ed such m films in which the adhesive of the first men-;tioned stickers was water-proctor unaflfected by water, the use of suchstickers renderible the rapid assembly of the cartri ge withoutthepossible introduction of moisture at this point. It has notbeenpossible, however, to utilize this t e of sticker at the free end of thefilm for t e reason that the permanently tacky adhesive will at onceadhere to the backing to use" a sticker with a water-soluble a hesive,such'as glue, at this free end of the film. The use of such a stickernecessitated the dampening of the end thereof which was .to be attachedto the film and involved certain disadvantages.

' We have tended particularly for use at-the free or un- I attache endof the film which overcomes 'these disadvantages in the process ofmaking the cartridge and which further'improves the cartridge as aphotographic article. It com- Lprisesa sticker carrying an adhesivecapable of bei afiected by water by which it may .be attac ed to thepaper when desired, but

carrying also a'portion coated with a permanent y tacky adhesive bywhichit may be applied to the film without the application 0 water; and thuspermitting the ll glinding'of all the elements in a. dry con- 'tion.

In the process 0 making a cartridge a spool 1 is laced in suitablewinding means, such as spindles-11, 12, which may be adapted forrotation by any desirable" mechanism, either hand actuated or automatic,a machine for o crating such spindles 'beingedisclosed in t e ndingapplication rial No. 516,229, fi ed Nov. 18, 1921,-of Jones, one of thepresent inventors."

If too little water is used the sticker will not adherefirmly. Moreover, while the stickers may be positioned by automaticmachinery, they are in practice placed by hand; and it is customary forthe operator to ress the sticker into adhesive contact wit the fingers.If this is not uniformly done over the surface, some parts will not bestuck, especially if too little water has been used. As the adhesivedries rapidly, its adherent qualities decrease. All of thesedifliculties are overcome by the permanently tacky adhesive; no water iscarried into the cartridge; no delay is desirable; and when the stickeris properly positioned on the film and carried into the roll, it will bepressed into firm adhesive contact by the pressure of the tight winding.

It is obvious that the cartridge as a photographic article is improved,since the possibility of the presence of undesirable moisture is greatlyreduced.

It is apparent that numerous modifications may be made in the form ofthe sticker and we have chosen certain of the more d'esirable ones forpur oses of illustration.

The two adhesive ands need not be so arated by an intermediate uncoatedportion and forms illustrative of this are shown in Figs. 5 and 6. InFig. 5 the two coatin 14 and 15, of waterproof and water-soluEl eadhesives respectively are extended from the borders of the supportingstrip 16 to meet at an intermediate oint 17, leaving no uncoatedportion.

This type ofl'ers certain manufacturingadvantages. v

It is not necessary that the two adhesive surface of the sticker strip.In Fig, 4 is shown a strip 22 having on one surface a border 23 of whichit is attached to the end 6' of the 3, and on the other surface and nearthe opposite edge a border 25 of dry water-soluble adhesive,

The adhesive which wedescribed .as waterproof or permanently tacky, isof a well known type such as is used for adhesive tapes of variouskinds. A typical composition includes rubber and-coal tar pitch with anysuitable softener such as benzol, gasoline or chloroform. We do notlimit ourselves to any particular composition since any 'adhesive thatis so slow drying as to' maintain its tackiness over a reasonable time,and the adhesive properties of which are unaffected by water iscontemplated as within the scope of our invention. Similarly when werefer to water-soluble adhesive, we intend to include any glue or pastewhich usually dries quickly and which becomes quickly adhesiveinthe'presence of moisture. I I

It is ap arent that while the sticker band is particu arly adapted forthe uses herein described, it is capable of other uses, and particularlfor 'use as the sealin band that is supplied at the tail end of t ebacking paper as sold by the manufacturer. We contemplate aswithin thescope of our invention all such modifications and equivalents'as fallwithin the following claims.

Having thus described. our invention, what we claim as new and desire tosecure by Letters Patent is:

1. A sticker for use in roll film cartridges comprising a strip offlexible material having along one edge a band ofadhesive capable ofbein affected by water and along the opposite e ge a band of water proofadhethe permanently adhesive type by 2. A sticker for use a. roll filmcartridges comprising a strip of flexible material having separatedbands of adhesive material thereon, one of said bands being ofwaterproof material and the other of material capable of being affectedby water.

3. A sticker band comprising a rectangular strip of paper having onesurface and border thereof a coatin of adhesive material capable ofwater and on the same surface and alon the opposite border a coating ofwaterproo ad- S gned at Rochester,
